METALLIC PILING.

SPECIFICATION forming part of Letters Patent No. 785,274, dated March21, 1905.

Application filed September 29, 1904:. Serial No. 226,598.

To (LZZ whom it mayconcern:

Be it known that I, MORITZ SoHLEUssNER, a subject of the Emperor ofGermany, and a resident of 8128 Bredeney, near Essen-onthe-Ruhr,Germany, have invented certain new and useful Improvements in MetallicPiling, of which the following is a specification.

The present invention relates to metallic piling, and especiallyto theclass of piling constructed of two rolled beams of channel sectionriveted together. The known piling of this kind is constructed in such amanner that when a row of piles is made the piles guide one anothervertically only, and when meeting obstacles the pile is likely tobe'displaced horizontally from the adjacent pile. In order to avoid thisobjection, it has been proposed to make piling by providing a tubularbody havin on one side a J shaped guide-rail and on t e other side twoL-shaped guide-rails. Piles of this kind can slide vertically andparallel to one another without horizontal displacement; but when rivetsare used for securing the guide-rails to the body only shortpile-sections can be produced, and if it is desired to obtain long pilesseveral sections must be combined to form the same. It is true that thiscombining of sections would not be necessary if screws were used forsecuring the guide-rails; but this said mode of securing is expensiveand does not afford much resistance.

I attain the object of my present invention by riveting two flangedchannel-beams together to form a pile and by providing interlockingguide-rails along the edges of the connecting-flanges. i

In the accompanying drawings, Figuies 1, 2, and 3 are horizontalsectional views of several embodiments of my improved piling.

Each of the piles A and B, Figs. 1 and 2, is made of two symmetricalrolled flanged channel-beams A A (or B B fitting together to form atubular body and connected by rivets O passing through their abuttingflanges a", (or b Each connecting-flange has a guide-rail a (1) Theguide-rails on each alternate one of the piles are spaced apart andpresented inwardly, as shown at :20, Fig. 1, while the guide-rails onthe other intermediate piles are in abutment and presented outwardly, sothat when piles of the two kinds A and B are driven down in interlockingengagement, as shown in the drawings, they slide vertically and parallelto one another without possibility of horizontal displacement.

The piling illustrated in Fig. 3 differs from that shown in Figs. 1 and2 only in that each pile has guide-rails presented inwardly on one sideand outwardly on the other side that is to say, the interlocking partson one side of each pile are like those on pile A, Fi s. 1 and 3, whileon the other side they are li e the'interlocking parts on pile B.

Having described my invention, what I .claim is 1. A piling comprising apair of symmetrical channel members, each member having a pair ofoutwardly-extending flanges consistipg of a straight inner portionabutting posing channel, member and a bent outer portion forming withthe flange of the opposing channel member an interlocking member adaptedto engage an adjacent piling.

, 2. A piling comprising a pair of symmetrical channel members, eachmember having a pair of oppositely-extending flanges integral therewith,said flanges havin a bent outer end, means for securing the flanges ofthe two members together intermediate of the channel portion and thebent flange por tion to form a tubular member and a pair ofoppositely-extending interlocking members,

the last-named members being adapted to interlock with the interlockingmembers of the adjacent-pilings.

The foregoing specification signed at Essenon-the-Ruhr this 1 9th dayofSeptember, 1 904.
